I'd rather give my time and money to a game that I find worth paying for rather than pirating, but you do you.
Also, pirated games, like any other Windows program, work on Wine. Maybe not all, but not all Windows software work on Wine anyway.
I've seen pirated games distributed for linux as an enormous shell script containing a 30GB binary blob that bundles the game along with wine. If it's stupid and it works, it's not stupid...
